ADSORMAT® open-system desiccator plugs are mounted on the vent nozzles of drums, KTC/IBCs and tanks. ADSORMAT® dries the column of air above the product in the container, as well as any humid air subsequently flowing in through the vent nozzle as the container is emptied. This prevents chemical reactions which may otherwise occur in a humid atmosphere. Each ADSORMAT® desiccant plug is fitted with a reversible humidity indicator, the colour change showing when its capacity limit has been reached.

Clariant's Container Dri® portfolio offers a broad line of container desiccants that offer versatile protection against damaging humidity and moisture during intermodal transport. Available in bags, poles and strips, these industry-leading products absorb up to three times their weight in moisture, and trap it as a thick gel that will not spill or drip. Preventing “Container Rain” A unique feature of Container Dri II desiccants is dew point control. Dew point is the temperature at which condensation starts to form on surfaces, such as container walls and roofs. By aggressively removing moisture from ambient air, Container Dri II products lower the dew point to prevent “container rain”, “container sweat”, or also known as “cargo sweat”, from damaging goods in transit. This system is highly effective in preventing the conditions that may cause mildew, warpage, corrosion, caking and other damage to agricultural products, bulk foods, powders, wood products, glass, furniture, automobile parts, leather goods, beans such as cocoa bean, and coffee bean, machinery and metal components. Container Dri II cargo desiccants can help manufacturers, shippers, distributors and other stakeholders protect brand equity, maintain their reputation for quality and safeguard revenues. Usage Scenarios The Container Dri II line of container desiccants are particularly valuable when: - there is a large volume of air requiring moisture removal - high levels of humidity are present due to climate, cargo or storage conditions - the container admits exterior air and humidity Food Shipments Container Dri II has already enjoyed success protecting cocoa bean shipments from moisture damage by providing the highest moisture absorption of any calcium chloride–based product, easily addressing the 65 percent or higher loading of calcium chloride recommended in the Federation of Cocoa Commerce Ltd. (FCC) guidelines for shipment of cocoa beans in containers. Read the full release here: Clariant Container Dri® II Desiccants Meet New FCC Guidelines for Cocoa Bean Shipments Sustainability - ECOTAIN ® Clariant's EcoTain ® label is awarded to products that are identified as best-in-class for sustainability and performance excellence to customers. Products are screened against 36 criteria across three dimensions: social, environment, and economic. Container Dri II delivered a positive benefit in all three, making Container Dri II the only cargo desiccant to carry an eco-label claim.

As one of the lightest solid materials available today, aerogels are manufactured through the combination of a polymer with a solvent, forming a gel. For buildings, the fiber-reinforced types are mainly used. In this paper, the changes both in the thermal performance and the material structure of the aerogel blanket are followed after thermal annealing. The samples are put under isothermal heat treatments at 70 °C for weeks, as well as at higher temperatures (up to 210 °C) for one day.

Sani Ibrahim2, Goh Teik Beng3 1Chemistry and Biology Division, School of Arts and Science, Tunku Abdul Rahman College, Jalan Genting Kelang, Setapak, 53300 Kuala Lumpur, Malaysia 2SaniChem Resources Sdn. Bhd., D/A Pusat Inkubator SIRIM, Bandar Baru Salak Tinggi, 43900 Sepang, Selangor 3The Drug Research Centre, Universiti Sains Malaysia, 11800 Minden, Penang, Malaysia. ABSTRACT A sampling and analytical method for the measurement of ethylene oxide (EtO) level in air was developed. The procedure was based on the entrapment of ethylene oxide in an activated silica gel adsorbent inside a sampling tube. The ethylene oxide was desorbed by distilled water and the eluent was analyzed by gas chromatography with flame ionization detector. Parameters such as breakthrough volume, method detection limit, desorption efficiency and storage tests for 14 days in ambient temperature and refrigerator were determined. Field samplings were performed at two factories in Kulim and Pulau Pinang respectively, which use ethylene oxide gas as sterilization substance. The desorption efficiency of ethylene oxide from silica gel tube was determined to be 87.8% over concentration range of 0.2 – 4.0 ppm in 3 liters of air sample. The method detection limit was determined to be 1.0 ppm whereas the precision of procedure was 10.7%. All the parameters were shown to be meeting OSHA requirements.

  • What Happens If I Eat Silica Gel?
    POISON ology SAFETY & FIRST AID TIPS FROM THE ARIZONA POISON AND DRUG INFORMATION CENTER What happens if I eat silica gel? If there's one thing most people know about silica gel, the unseen substance that occupies those little white packets inserted in new shoe boxes, purses, and Asian snack foods, it's that you're not supposed to eat it. Ususally, the scary warning "do not eat" is displayed across the packet. Often it is accompanied by the command, "throw away." In case that's not clear enough, a few varieties have a skull and crossbones. OK, so, what happens if you eat it? Nothing. Silica gel is a form of the naturally occurring mineral silicon dioxide, better known in its granular form as sand or in crystals as quartz. It absorbs up to 40 percent of its weight in water and has been widely used to remove moisture by placing it inside containers to prevent the contents from getting damp. Used in everything from museum display cases to electronic equipment packaging to boxes of seaweed, it is popular in part because—contrary to the warnings—it is essentially harmless. Indigestible, it passes through the body and comes out looking much the same as when it went in. So why all the doom and gloom on the labeling? Because a surprising number of people, especially children, mistake the packets for food. In 2009, some 38,000 people reported swallowing these packets, according to the American Association of Poison Control Centers. Of those, 34,000 were under the age of 6.
